Abstract: FIELD: rocket construction. 
     SUBSTANCE: invention relates to rocket engineering and can be used for production of mixing heads of injector type of combustion chamber (CC) of liquid-propellant engine (LPE). Unit of nozzle assembly of mixing head for soldering, high-temperature soldering in vacuum, quality control, testing for strength and tightness, and when detecting leakage (non-solder) of certain nozzles with mixing head bottoms, they are locally soldered. Said soldering is performed by electron beam under conditions of deep vacuum at fixed position of mixing head, acting on re-laid solder rings of solder around each non-soldered nozzle with refocused electron beam with circular low-frequency scanning. Local heating along the perimeter of the nozzle is created, which ensures high cleanness without oxidation of surfaces in the heating zone and density of the connection due to mixing of molten solder with a low-frequency beam and gas drawing by vacuum, as well as safety of nozzles previously soldered to the bottoms. After the next nozzle is soldered, the program control system automatically cuts off the electron beam and melts the solder. Then, another nozzle is moved to move the manipulator or deflecting system of the electron-beam gun; after repeated soldering, the mixing head is repeatedly tested. 
     EFFECT: invention improves quality and reduces labor intensity when making a mixing head of a liquid-propellant engine combustion chamber.

Compression fixation ring with dynamic compression for the surgical management of complex shifted acetabular fractures has the shape of an open hemisphere and contour corresponding to contour of cartilaginous surface of cotyloid cavity comprises two ends, on which has one hole and two grooves, inner and outer surfaces, an upper inlet opening and a lower opening, holes along the whole length of the wall surface of the ring for insertion of fixing screws into the wall of the cotyloid cavity. Holes are arranged relative to recesses of the wall edge of the ring of the upper inlet in staggered order and recesses along the edge of the wall along the whole perimeter of the ring for introduction of fixing screws through them into the wall of the cotyloid cavity and its columns. Ring has a crest located parallel and along the perimeter of the lower hole of the ring, which is located above the inner surface of the ring, and has a crest located parallel and along perimeter of upper inlet hole of ring, which is located above inner surface of ring. Ring has flanges with holes arranged horizontally along the edge of the wall of the ring of the inlet hole horizontally or along the ends of the ring ends, or vertically at the ends of the ring ends. Holes of flanges have threads for threaded stud screwing in. Thread in each flange has a reverse direction, which ensures: when the stud is twisting, the ends of the ring will approach each other, and with the reverse rotation of the pin, the ends of the ring will diverge. Holes for introducing fixing screws into the wall of the acetabulum are made with conical or cylindrical recesses around the holes and with radial cuts, wherein location of one of such holes on one end of ring corresponds projection, after installation of ring into cotyloid cavity, point of connection of horizontal branch of pubic bone and cotyloid cavity, and location of the other of such holes on the other end of the ring corresponds projectively, after installing the ring into the cotyloid cavity, the junction of ischial bone and the cotyloid cavity.
